During the operation of synchronous brushless DC motor, it is usually necessary to sample the phase current of the three-phase coil of the motor to realize the closed-loop control of the motor. In the traditional three-phase current sampling method, three-resistance or double-resistance is often used to sample the motor current. However, the double-resistance and three-resistance sampling control circuit is complex and the manufacturing cost is high. Therefore, the method of using single resistance to sample the three-phase c...

High-precision Mn-Cu resistance alloy narrow ribbon is the core resistance material of various electrical instrument shunt elements. Manganese copper resistance can be used in all kinds of instrument relay, automobile relay, meter relay and so on. In the traditional process of resistance element, Mn-Cu flat strip resistance element is made up of large size Mn-Cu sheet (or strip) after punching forming and copper guide plate is made up of overlap welding. The resistance element of mn-Cu flat strip is composed of large-size Mn-...

In the existing technology, resistance testing instruments are widely used in laboratory testing or production line sampling. The connection end of the resistance tester connects the two terminals of the resistance. The resistance tester displays the resistance value. Manual single measurement can not achieve continuous measurement and mass resistance measurement. The efficiency is low. A continuous automatic resistance testing device fix the two ends of the resistance into a strip resistance belt, place it on the transmissio...

After all the process of chip resistance manufacture, packing will be carried out and placed on the carrying belt to form a strip. In the packaging, there will be some phenomena such as fragmentation, mixing, setting-up, inversion, placing, empty material, jumping material, material missing angle, carrying belt contamination, carrying belt damage, and so on. A bad resistance flowing to the client terminal and attached to the circuit board will result in the bad quality of the final product, and a security risk. Because of a b...

Precision resistor is a kind of very important resistor. Its precision, stability and low temperature drift design bring this resistance a superior market competitiveness. The accuracy of precision resistance represents the accuracy of resistance value. In fact, the accuracy is affected by many factors, such as ambient temperature changes, , self-heating due to self-energizing, pressure or tension from the PCB, external moisture, even corrosive gases, or welding, pulse, overload, static electricity, radiation and so on. Thes...

The precision chip resistor adopts the manganese-copper strip as the raw material. It is relatively complex to manufacture the resistor of the package size 2512 within 1% tolerance. First of all, the manganese-copper strip is stamped into the required resistance pattern by precision stamping. The target resistance value is set, correcting the center value according to the upper and lower limits of the target resistance value so as to ensure that all products are controlled within the upper limit of the specification. To modif...

There are many kinds of resistors in our life, each kind of resistor has its own characteristics and technical advantages. Common ones are high-power resistance, chip resistance, plug-in resistance, precision resistance, brake resistance and so on. In charger products, wire wound resistor use the most. So why do chargers use wire wound resistor, what are the advantages of them? The common wire wound resistor, made of a resistance alloy wire, is generally made of a nickel-chromium wire or a manganese copper wire. Apart from t...

Metals used as resistive materials should have the characteristics of high electrical conductivity, sufficient mechanical strength, not easy to oxidize, not easy to corrode, easy to process and weld. The resistance material has a great influence on the resistance performance. Generally the resistance materials used in the high-end precision resistor are all high precision type. This kind of precision alloy material can make the performance of precision resistance more superior, the precision higher and temperature drift small...
